To al 107mm it may conca-nk',

Be it known that I, GEORGE CKELHAUPT,

of the city of New York, borough of Manhattan, in the county and StateoljNeW York, have invented a new and Improvleld Furnace for HeatingSoldering-irons, of which the following is a full, clear, and exactdescription.

The invention relates to furnaces used by plumbers and other'meehanicsg'and its'object is to provide a new and improvedfurnace for heatingsoldering-irons and the like tion of the improvement vonV the line 1 1in Fig. 2. Fig. 3 is a sectional plan view of the same on the liuc 2 2in Fig. 1, and Fig. 3 is a transverse section of the same on the line 33 in Fig. 1.

The improved furnace for heating soldering-irons is provided withaportable casingA, preferably made of sheet'metal and having legs A' anda firebrick lining l5 in the upper portion, thc front and bottom ofthecasing being open, to permit'of introducing the soldering-irons throughthe openfront and to allow ai r to pass through the open botto'm to aburner U. A burnerCextendsinalongitudinaldirection in the casing belowthe fire-brick lining, as is plainly indicated in the drawings, and itconsist-s of two longitudinal pipes C and C, connected with each otherat their ends by cross-pipes C:i t1, of which the pipe Gais su pportedin a suitable bracket D, attached to a.

thereof.

cross-bar A2 of thc easing at'thc open front The rear cross-pipe C4terminates in a vlongitudimtlly-e1-itending pipe C, supported in andextending through the rear end of the casing A, and in the bottom ofthis pi pe C5 is formed a large air-inlet C6 for allowing nir topassinto the pipe and mix with thegas supplied through a pipe E, connectedwith a suitable source'of gas-supplynnd opening in a small jet into theextreme rear ond of thc pipe C", as ls plainly shown ln Fig. 1. A

ined February 3,1899'. sean No.7o4,a'11. (Nomaden valve Eon thesupply-pipe E serves to regulate the amount of gas allowed to pass intothe pipe C5, andv thus insures a proper mixing ofl gas and air. Thelongitudinal pipes C' and C2Lare provided at their inneropposite sideswith rows of apertures C7 for the iniiammable mixture of gas and air topassl through in small jets, said apertures "being protected againstscales or other small par tioles by overhanging projections or 'lugs Cs,secured on said pipes. (See Fig. 3.)

Now it is evident'that when 'the valve E is.

opened a vmixture oigas and air is formed in the pipe C5, and thismixture Hows from 'said pipe, through the pipe Cilinto the vlongitudinalpipes C C2 to issue from the 'same in small jets through the aperturesC7, and this mixture is -ignited at theapertures to produce jets offlame for'heating the irons supported'above the' b urneronga' pair ofsupports F, each made with two upwardly-curved arms'F' F2, adapted torest on the to'p of the pipes C' C2, respectively.- The middle portionsF3 of the arm-supports F are'pivotally connected withdownwardly-extending arms G,secured on alon gitudinally-extendin g shaftII, mounted to turn and to slide in suitable bearings A'S'Ai, arrangedon the casing.

The forward end of the shaft H projects somewhat-at the'front of theeasing` and' is provided at its end with an arm I for turning saidsh'aft to swing the arms Geither to thc right or to the left and movethe arm-supports F from their normal central position (show'n in fulllines in Fig. 3) into a sirlewise position, as Vindicated in dottedlines in Fig. A

3, so that only one of the arms F' or lfistnnds midway between the twovpipes C' C'- to bring a soldering-iron supported on said curved armdirectly over the jets of llame issuing from the 'pipes C' C.

The arm-supports F can be locked in 'their normal position (shown infull lines in Fig.

3) by sliding the shaft II rearwardly to bring'l akey II on said shaftin engagement with a corresponding aperture formed in the benring A, sothat the shaft cannot be turned. (See Figs. 1 and 2.) v'

When it is desired to change the position of the arm-supports, theoperator pulls the hu-lnllel outward and slides the shaft ll in thc namedirection, so as t'o discngago the key IOO H' from the aperture in thebearing A to per- .mit of turning the shaft H, and thus bring either setof curved arms F' or F2 between the burner-pipes C andC2.

The overhanging projections C8 are preferably provided with cut-outportions C9 (see Fig. 2) for the arms F' F2 to pass into when moved intoa middle position, as above explained.

Below the shaft II is arranged a pan J, removably supported on bracketscarried by the legs A', said pan being adapted to receive any dross orscales or other matter falling off the solderingirons placed on thesupports F. "When the supports are in the position shown in Fig. 3, twosoldering-irons can be placed on the two sets of curved arms F and F2and heated by the jets of flame issuing from the pipes C' and C2, asabove explained, and when it is desired to heat a single iron veryquickly the operator shifts the shaft H, as previously explained, byunlocking the shaft from its bearing and swinging the arm I over to oneside, by striking the arm with the solderingiron, and then placing thesoldering-iron into the set of curved arms F' or F2, extending betweenthe pipes C' and C2.

Apfurnace constructed in the manner described is portable and by meansof a rubber tube or the like can be connected by the pipe E with thegas-pipe in a building for supplying the-necessary amount of gas for theinflammable mixture, as above explained.

The top of the casing A may be provided with an outlet-opening K, asindicated in Fig. l, so that when the cover of this opening is removedan increased draft is had for the burner. 4

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- 1. A furnace,comprising acssng, a burner in the ,casing and consisting of a pluralityof pipes, a support consisting of. oppositeiy-extending arms, a shaft onwhich the support is mounted, the said 'shaft being adapted to rock inthe casing, and means for locking the shaft to hold the support in acentral position relatively to the burner, substantially as specified.

2. A furnace for heating soldering-irons, comprising a casing open atons end and vat the bottom, a burner arranged in said casing and formedof a plurality of apertured pipes connected with a mixing-pipe hayiuganairinlet and a gasulet, s pair of supports each in the form of' ti'ocurved' arms ads ted to rest on said 'apertnred pipes, arms or thesupports, and a shaft moued to turn and to carry said arms,substantially-as shown and described.

3. A furnace for heating soldering-irons, comprising a casingopen at oneend and lat the bottom, a burner arranged in said easing and formed of aplurality of apertured pipes connected with a mixing-pipe having auairinlet and a gas-inlet, a pair of supports each in the form of twocurved arms adapted to rest on said apertured pipes, arms for thesupports, a shaft mounted to turn and 'to carry said arms, and means,substantially as described, for locking said shaft against rotation, asset forth.
